[CrockettRocket]

Howard died second with the help of me and tying a rope around his neck. I told him: "If you don't kill yourself, I'll kill you and your family."

Blue truth incomplete: How did you get out of room and then lock it? (Also, you are not part of my story, sorry XD)

[propheon]

 alicia commited suicide because of lucy

[Fippe94]

Incomplete. I have already stated why Alicia couldn't really commit suicide. (The killer left the room after Alicia died)

[propheon]

the owner have a wife

[Fippe94]

...wat. That doesn't even remotely solve any mystery. Please.
A blue statement must provide a complete theory on how a mystery is possible for humans.

So you are telling me that
1- no one we know pushed the key under the door
2-  A) nobody entered during the night
     B) nobody entered in the day.

So, it is neither someone we know, nor someone that we do not know that pushed the key under the door, therefore, the key did not get pushed under the door.

There was another guest in the hotel which was not mentionned in the story. It is that guest that threw the key under the door

[Fippe94]

The only guests staying at the hotel are you, Lucy, Alicia, Bill and Charlie.

[MyNameIsJoey]

There was someone else in the hotel which was not mentionned in the story. It is not a guest, it could be an employee or the owner's wife or whatever. That person threw the key under the basement door.

[Fippe94]

As far as the Howard (the owner) knew, there was no person in the hotel besides those mentioned in the story.
